I get up early, but my brother gets up late. 二、连词分类： 并列连词 从属连词—— 连词：and, but, or, so, (for) 连词词组: either…or, neither…nor, not only…but also, both…and, (as well as) that，whether, if, unless, while / when, until, because, so that, so…that, though/ although, even if, as…as 等 三、用法 1.并列连词 --- 连接具有并列关系的词，短语或句子。 常见的有： (1)表并列关系的and, both…and, not only…but also, neither…nor，as well as（也，和）等。 (2)表选择关系的or, either…or等。 (3)表转折关系的but, however等。 (4)表因果关系的for, so等。 考点一： 1）判断改错： They sat down and talk about something. They started to dance and sang. I saw two men sitting behind and ate there. 　 F F F eating sing talked and (“和，并且”) 与 or (“否则”) “and” 连接平行结构。 （1）肯定句中用“and” 表“和”； （2）否定句中用“or”表“和” 。 2）翻译：① 我喜欢英语和数学。 ② 我不喜欢英语和数学。 I like English _____ math. I don’t like English ____ math. and or = Study hard, _____ your math will be worse. 3）用 “and” 或“or” 填空： Study hard, _____ your math will be better. and or “and”意为“这样，那么”； “or” 意为 “否则” 。 表转折的连词but 和however： e.g. (他努力工作，但以失败告终。) He worked hard, ______ he failed at last. He worked hard. _________, he failed at last. 区别: but 后没有逗号，直接连接分句； however 后有逗号相隔，可放句末。 but However 考点二 ： 观察句子 ： （1）Although he is over sixty, but he works as hard as others. 改为：Although he is over sixty, he works as hard as others. 或 He is over sixty, but he works as hard as others. （2）“Because John was ill, so I took him to the doctor.” *although/ though 和but这两个关联词不能同时用。 ??? 同样，此句错误， because 和 so 等关联词都不能同时使用。 考点三 ： either A or B “或者A或者B” neither A nor B “既不A也不B” not only A but also B “不仅A而且B
